UNITED STATES PATENT OFFICE.

FRANK WHEATON, or BROOKLYN, NEW YORK.

VENTILATOR FORFEEi J-BAGS.

SPECIFICATION forming part of Letters Patent No. 294,421, dated March 4,1884.

Application filed June 13, 1862.

To a whom it may concern-.-

Be it known that I, FRANK WHEATON, of

Brooklyn, in the county of Kings and State of I New York, have inventeda new and I111: proved Ventilator for Fodder-Bags, of which thefollowing is a full, clear, and exact description.

The object of my invention is toprovide a new and improved ventilatorfor fodder-bags for feeding horses.

The nature of the invention consists in a perforated bottom orventilator for feed or fodder bags, said bottom or plate having asurrounding rim provided with a flange secured to the bag, substantiallyas hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan View of myimproved ventilator for fodder-bags. Fig. 2is a cross-sectional elevation of the same on the line mm, Fig. l.

A metal plate, A, is provided with perforations a, and theseperforations are surrounded by a raised ring or rim, B, which is stampedor. pressed up on theplate A, the perforated part of the plate and theraised rim being made integral. The rim B is provided with a horizontalapertur'ed flange, B,-having a series of apertures, through which rivetsO are passed for securing this ventilator on the material D of which thebag is made, or the ventilator can be secured on the bag by sewing.

Renewed July 21, 1883. (N0 model.)

ventilator is to be flush with the inner surface of the bag.

This ventilator is of very simple construction, as it-is made of onesingle piece of metal, and is thus much more durable than theventilators in which the netting or perforated plate is soldered orriveted to the rim or ring. Slots may be provided in place of theperforations a. The perforations and the rim are punched or stamped outin a'single operation.

By providing the rim B of the ventilator A with the broad surroundingflange Bit will be observed that a greater area of fastening-sur- .faoefor its attachment to the bag is furnished and an extended bottomprovided to the bag, while by its occupying a relatively raised plane,the lower edge of the material is enabled to be fastened thereto on itsunder side, to isolate the fastening-edge of the material from thecontents of the bag and from the action ofthe horses mouth.

- Having thus fully described my invention, what I claim as new, anddesire to-secure by Letters Patent, is

In a feed or fodder bag, the combination, with the bag portion D, of theperforated bottom or plate A, having the raised surrounding rim B,provided with a horizontal apertured flange, B, substantially as shownand described, and forthe purpose set forth.

FRANK WHEATON.
